Medical therapy for glaucoma: A review.

Area of Science:

• Ophthalmology
• Pharmacology
• Glaucoma Research

Background:

• Medical management of glaucoma traditionally relies on modifying intraocular pressure (IOP) via pharmacological targets.
• Recent advancements have broken a period of stagnation in glaucoma treatment development.
• The landscape of glaucoma therapy is rapidly evolving with new drugs and delivery methods.

Purpose of the Study:

• To review the evolving pharmacological and surgical strategies for glaucoma management.
• To highlight the potential and limitations of IOP-independent neuroprotection.
• To emphasize the need for evidence-based assessment of emerging glaucoma treatments.

Main Methods:

• Review of current pharmacological targets and novel ocular hypotensive drugs.
• Evaluation of innovative drug delivery systems, including intracameral and sustained methods.
• Assessment of IOP-independent neuroprotection strategies and their translational challenges.
• Analysis of emerging surgical interventions like selective laser trabeculoplasty and micro-invasive glaucoma surgery.

Main Results:

• A significant burst of innovation has introduced new ocular hypotensive drugs and advanced delivery methods.
• IOP-independent neuroprotection strategies show promise in preclinical models but have limited clinical translation.
• Traditional topical medical therapy faces competition from surgical and sustained delivery options.

Conclusions:

• The expanding armamentarium for glaucoma requires rigorous scientific evaluation.
• Evidence-based assessment is crucial for clinicians to optimize vision preservation and patient quality of life.
• The future of glaucoma management involves a multimodal approach integrating pharmacological, surgical, and potentially neuroprotective strategies.
